WINDOW.

PECIFICATION forming part of Letters Patent No. 458,929, dated September 1, 1891.

Application file April 21, 1891. Serial No. 389,826. (No model.)

T0 all wh0m it may concern:

Be it known that I, JOHN WILSON, a citizen of the United States, residing at Bartlett, in the county of \Vashington and State of Ohio, have invented a new and useful Vindow, of which the following is a specification.

This invention relates to carpentry, and more especially of that class thereof known as windows; and the object of the same s to produce certain improvements in devices of this character.

To this end the invention consists in the details of construction hereinafter more fully described and claimed, and as illustrated on the sheet of drawings, whercin Figure 1 is a perspective viewof a windowfran1e embodying 1ny improvements and viewed from the outside, one of the beadsbeing broken away and a portion of the frame beifigin perspective section. Fig. 2 is a crosssection taken above the grooved pulleys. Fig. 3 is an enlarged perspective detail of one of the cords,its hook, and the plate which is secured to the edge of the sash.

Referring to the said drawings, the letter F designates the window-frame, in Which move the sashes S, and 0 are cords leading from these sashes over grooved pulleys G, j ournaled in the frame and conncctcd to sashweights W, all as is usual in devices of this character.

Coming now to the present invention, the letter P designaces a plate sccured, as by screws, to the edge of the sash and having an eye I, and 11 is a hook connected to the end of the cord C and detachably engaging this eye. The plate P projects from the edge of the sash at right angles to the plane of the glass, and, as snown in Fig. 3, the eye in the plate is just beyond the outer face of the upper sash.

B is the usual bead between the two sashes, and L is an L-shaped strip secured to the inner face of the frame in st 1chmannerthat the plate P shall pass beneath the free edge of the strip. In the inner'face of the framcbeneath the free edge of the strip is a narrow vertical groovc V. Referring to Fig. 2, it will be seen that the strip L is of slightly-diiteb from the .eycs I.

cnt construction--that is to say, instead of being secured to the inner face of the frame, said trame is recessed and the strip extends into and is secured in Said recess, although the free edge of this strip also covers the plate P, carried by the sash.

In operation the eords leading frorn the weights pass over the grooved pulleys G and extend downwardly in the vertical grooves V to the hooks Il, which are detachably connected with the plates P, and the weights move oppositely to and counterbalance the weight of the sashes in an obvious manner. A window-frame of tl1is construction courpletely conceals the sash cords and the grooved pulleys, and thereby not only adds to the appearan ce of the whole,but also prevents the accumulation of dust in the sash-balancing deviccs. At the same time, when it is desired to remove a sash, the strips L are taken from the frame and the hooks H diseonnected The sash can (heu be readily removed.

Var-ions changes may be made in the details of construction without departing from the spirit of my invention.

What is claimed as new is 1. The combination,with the window-frame having a narrow vertical groove,an L-shaped strip securcd to said trame with its free edgc covering the groove, a bead, and a sashmoving between said bcad and the free edge of the strip, of a plate secured to the edge of the sash and projecting across said groove and beneath the free edge of the strip, a grooved pullcy journaled in the frame at the upper end of the groove, a cord leading from said plate through the groove and over the pulley, and a weight connected to the cord, substantially as described.

2. The eombination,with the window-franre having a vertical recess and a narrow vertical groove, an L-shaped strip, one edge of which is secured within said recess and the othcr edge of which covers said groove, a bead, and a sash moving between said bead and the free edge of the strip, of a plate secured to the edge of the sash and projecting beneath said free edge, a grooved pulley journaled in the frame at the*upper end of the -my own I have hereto affixed my signature in groove, a hook detachably engaging au. eye presenee of two witnesses. in Said plate, 5 cord leading from said hook through the groove and over the puley, and WILSON 5 a weight connected to the cord, substancially Wimesses:

as hereinbefore described. D. L. FAWCETT,

In testimony that I clam the foregong as T. D. CUMMINGS.
